Two electrons are found in the same atom. One has the quantum number set (2, 1, 0, +½), and the other has the quantum number set (2, 0, 0, +½). They share the:

A. same sublevel, but are in different orbitals.
B. same orbital, but have different spin directions.
C. same energy level, but are in different sublevels.
D. same type of sublevel, but are found in different energy levels.
